Hi all. First Thanks for Zope, it's and incredible piece of software. I'm a newbie on Zope but I'm very impressed about its posibilities. At this moment I have a problem trying to use the External Editor. I'm using Zope (specifically Plone) to put online TeXmacs documents. The idea is to define TeXmacs as the external editor for *.tm files. The thing goes fine the first tieme but after that the *.tm files (wich are plain text documents with tags "ala" TeX or HTML). The problem is the second time that the documento edited is opened again. Now the file is not rendered by TeXmacs as nativa *.tm files but instead is show as a *.tm.txt plain text file. How can I evite this? Please answer me with copy to my e-mail, because I have not suscribe this e-mail address to the zope mailing list. Thanks a lot, Offray
